Abstract

descreve-se uma composição aquosa de pasta de cimentação e um método de uso da mesma, para cimentação de uma tubulação ou tubo de revestimento num furo de perfuração usando uma composição aquosa de pasta de cimentação que compreende (a) um cimento hidráulico, (b) uma metilhidroxietil celulose (hemc) que tem uma substituição molar de óxido de etileno (eo ms) de 0,16 a 0,22 e um grau de substituição de metila (m ds) de 1,35 a 1,45, (c) água e opcionalmente (d) um ou mais outros aditivos convencionalmente adicionados a composições aquosas de cimentação úteis na cimentação de tubos de revestimento no furo de perfuração de poços. de preferência, a composição aquosa de pasta de cimentação é bombeada para baixo para o referido tubo de revestimento, bombeada para cima para o anular circundando o referido tubo de revestimento até que a referida composição aquosa preencher essa porção do anular que se deseja vedar e em seguida, mantendo a referida composição aquosa de cimentação no lugar até que o cimento assentar.An aqueous cementitious slurry composition and a method of use thereof for cementing a casing pipe or pipe into a borehole using an aqueous cementitious slurry composition comprising (a) a hydraulic cement, (b) ) a methylhydroxyethyl cellulose (hemc) having a ethylene oxide (ms ms) molar substitution of 0.16 to 0.22 and a degree of methyl substitution (m ds) of 1.35 to 1.45, (c ) water and optionally (d) one or more other additives conventionally added to aqueous cementing compositions useful in cementing casing pipes in the well borehole. preferably, the aqueous cementitious slurry composition is pumped down into said casing tube, pumped upwardly into the annular surrounding said casing tube until said aqueous composition fills that portion of the annular to be sealed and in then holding said aqueous cementation composition in place until the cement settles.
